What Integrated Management Services does

Integrated Management Services, doing business as IMS Engineers, is a full-service consulting, engineering, management and operations firm headquartered in Houston, Texas. Founded in 1996 by John D. Calhoun, Ph.D. and Rod L. Hill, P.E., the firm delivers planning, civil, environmental, transportation, structural, water resources, and water/wastewater engineering; program and construction management; and design engineering and construction phase services. It maintains offices in Houston and Dallas (TX), Greenville, Jackson, and Natchez (MS), Memphis (TN), New Orleans and Shreveport (LA), Baltimore (MD), and internationally in Addis Ababa (Ethiopia), East Coast Demerara (Guyana), and Accra (Ghana), and is recognized as one of the largest African-American owned and operated engineering firms in the US.

IMS operates a project-based professional services business model, generating revenue through contract engagements priced on a quote-driven basis. It serves a primarily government client base — local, state, federal, and international public agencies — alongside private industry ranging from locally owned businesses to Fortune 500 companies. The firm's go-to-market combines direct engagement with government bodies and sub-consultant positioning with major engineering primes such as WSP and Atkins North America. Notable engagements include design engineering for the Houston Waterworks Team's 320 mgd Northeast Water Purification Plant Expansion, General Engineering Consultant services for TxDOT's Southern Gateway Project, construction supervision of the 51-km Dembidolo-Mughi Road Project for the Ethiopian Roads Authority, and a $3.525 million contract for design review and construction supervision of Ghana Highways Authority's Tamale-Walewale Road. The firm operates as an independent private company with 101-250 employees and no disclosed external institutional ownership, M&A activity, or funding history.
